Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the object of the invention is to show a device with which a gentle catching or braking of bodies after a free fall is possible.
  • the device according to the invention enables gentle catching and braking of bodies at the end of a free fall, i. H. a gentle destruction of the kinetic energy of such bodies and is particularly suitable for use in physical examinations, but also in other areas of science and technology, where bodies are subjected to a free fall.
  • FIG 1 is a shaft of a drop tower which extends in the vertical direction with its axis.
  • the lower, open end 2 of the shaft 1 is arranged above a transport device 3, specifically above an obliquely downward section 4 'of a conveyor belt 4 of the transport device 3.
  • the conveyor belt 4 is continuous, self-contained and guided over several rollers 5 and additional guides and continuously driven with at least one of the rollers 5 in the direction of arrow A.
  • the conveyor belt 4 which is made, for example, of a rubber or plastic material usually used for conveyor belts with a fabric insert, has a width in the direction perpendicular to the drawing plane of the figure, which is at least equal to the horizontal cross-sectional dimension of the falling body 7 in this axis direction running perpendicular to the drawing plane .
  • the section 4 'of the conveyor belt 4 has, at least in the area immediately below the opening 2, an inclination with respect to the vertical which corresponds to an angle a which is equal to or less than 45 ° and opens upwards in the vertical direction.
  • section 4 ' In the direction of rotation A, section 4 'is followed by a section 4' '' leading obliquely upwards via an arcuate deflection area 4 ''.
  • the conveyor belt 4 In the deflection area 4 ′′, the conveyor belt 4 is guided on both sides by keeping the central area of this conveyor belt clear through guides (not shown in more detail).
  • the conveyor belt 4 At the end of section 4 '' ', the conveyor belt 4 is deflected downwards by means of a roller 5 and returned to this section via three further rollers 5, one of which is located at the beginning of section 4'.
  • a section 6 '' is followed by a braking section 6 such that the transport surface formed by the upper side of the conveyor belt 4 in section 4 '''merges into a surface of the braking section 6 at substantially the same level.
  • the braking section 6 is, for example, of a roller conveyor, the rollers of which, for. B. are partially braked, or formed by a slide.
  • the conveyor belt 4 is driven in the direction of arrow A at a speed which is approximately equal to the speed which a body 7 falling freely in the shaft 1 has at the opening 2 of the shaft 1.
  • This body 7 then falls on the section 4 'of the conveyor belt 4 and is initially carried along by the conveyor belt essentially without braking its speed and then passes via the section 4' '' to the braking section 6, in which a gentle braking of the speed of the body 7 or a gentle annihilation of the kinetic energy of the body 7 takes place.
